6 vmware_host_selinux - Security Enhanced Linux Policy for the
7 vmware_host processes
8
10 Security-Enhanced Linux secures the vmware_host processes via flexible
11 mandatory access control.
12 The vmware_host processes execute with the vmware_host_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep vmware_host_t
20
24 The vmware_host_t SELinux type can be entered via the
25 vmware_host_exec_t file type.
26 The default entrypoint paths for the vmware_host_t domain are the fol‐
28 lowing:
29 /opt/vmware/(workstation|player)/bin/vmnet-natd, /opt/vmware/(worksta‐
31 tion|player)/bin/vmnet-dhcpd, /opt/vmware/(worksta‐
32 tion|player)/bin/vmware-nmbd, /opt/vmware/(worksta‐
33 tion|player)/bin/vmware-smbd, /opt/vmware/(workstation|player)/bin/vm‐
34 net-bridge, /opt/vmware/(workstation|player)/bin/vmnet-netifup,
35 /opt/vmware/(workstation|player)/bin/vmnet-sniffer, /opt/vmware/(work‐
36 station|player)/bin/vmware-smbpasswd, /opt/vmware/(worksta‐
37 tion|player)/bin/vmware-smbpasswd.bin, /usr/sbin/vmware-guest.*,
38 /usr/lib/vmware-tools/sbin32/vmware.*, /usr/lib/vmware-
39 tools/sbin64/vmware.*, /usr/bin/vmnet-natd, /usr/bin/vmware-vmx,
40 /usr/bin/vmnet-dhcpd, /usr/bin/vmware-nmbd, /usr/bin/vmware-smbd,
41 /usr/bin/vmnet-bridge, /usr/bin/vmnet-netifup, /usr/bin/vmnet-sniffer,
42 /usr/bin/vmware-network, /usr/bin/vmware-smbpasswd, /usr/bin/vmware-
43 smbpasswd.bin, /usr/lib/vmware/bin/vmware-vmx

46 SELinux defines process types (domains) for each process running on the
47 system
48 You can see the context of a process using the -Z option to ps
50 Policy governs the access confined processes have to files. SELinux
52 vmware_host policy is very flexible allowing users to setup their
53 vmware_host processes in as secure a method as possible.
54 The following process types are defined for vmware_host:
56 vmware_host_t
58 Note: semanage permissive -a vmware_host_t can be used to make the
60 process type vmware_host_t permissive. SELinux does not deny access to
61 permissive process types, but the AVC (SELinux denials) messages are
62 still generated.
63
66 SELinux policy is customizable based on least access required.
67 vmware_host policy is extremely flexible and has several booleans that
68 allow you to manipulate the policy and run vmware_host with the tight‐
69 est access possible.
70 If you want to dontaudit all daemons scheduling requests (setsched,
74 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
75 Enabled by default.
76 setsebool -P daemons_dontaudit_scheduling 1
78 If you want to control the ability to mmap a low area of the address
82 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
83 the mmap_low_allowed boolean. Disabled by default.
84 setsebool -P mmap_low_allowed 1
86 If you want to allow unconfined executables to make their heap memory
90 executable. Doing this is a really bad idea. Probably indicates a
91 badly coded executable, but could indicate an attack. This executable
92 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
93 echeap boolean. Disabled by default.
94 setsebool -P selinuxuser_execheap 1
96
100 The SELinux process type vmware_host_t can manage files labeled with
101 the following file types. The paths listed are the default paths for
102 these file types. Note the processes UID still need to have DAC per‐
103 missions.
104 file_type
106 all files on the system
108
111 SELinux requires files to have an extended attribute to define the file
112 type.
113 You can see the context of a file using the -Z option to ls
115 Policy governs the access confined processes have to these files.
117 SELinux vmware_host policy is very flexible allowing users to setup
118 their vmware_host processes in as secure a method as possible.
119 STANDARD FILE CONTEXT
121 SELinux defines the file context types for the vmware_host, if you
123 wanted to store files with these types in a different paths, you need
124 to execute the semanage command to specify alternate labeling and then
125 use restorecon to put the labels on disk.
126 semanage fcontext -a -t vmware_host_exec_t '/srv/vmware_host/con‐
128 tent(/.*)?'
129 restorecon -R -v /srv/myvmware_host_content
130 Note: SELinux often uses regular expressions to specify labels that
132 match multiple files.
133 The following file types are defined for vmware_host:
135 vmware_host_exec_t
139 - Set files with the vmware_host_exec_t type, if you want to transition
141 an executable to the vmware_host_t domain.
142 Paths:
145 /opt/vmware/(workstation|player)/bin/vmnet-natd,
146 /opt/vmware/(workstation|player)/bin/vmnet-dhcpd,
147 /opt/vmware/(workstation|player)/bin/vmware-nmbd,
148 /opt/vmware/(workstation|player)/bin/vmware-smbd,
149 /opt/vmware/(workstation|player)/bin/vmnet-bridge,
150 /opt/vmware/(workstation|player)/bin/vmnet-netifup,
151 /opt/vmware/(workstation|player)/bin/vmnet-sniffer,
152 /opt/vmware/(workstation|player)/bin/vmware-smbpasswd,
153 /opt/vmware/(workstation|player)/bin/vmware-smbpasswd.bin,
154 /usr/sbin/vmware-guest.*, /usr/lib/vmware-tools/sbin32/vmware.*,
155 /usr/lib/vmware-tools/sbin64/vmware.*, /usr/bin/vmnet-natd,
156 /usr/bin/vmware-vmx, /usr/bin/vmnet-dhcpd, /usr/bin/vmware-nmbd,
157 /usr/bin/vmware-smbd, /usr/bin/vmnet-bridge, /usr/bin/vmnet-neti‐
158 fup, /usr/bin/vmnet-sniffer, /usr/bin/vmware-network,
159 /usr/bin/vmware-smbpasswd, /usr/bin/vmware-smbpasswd.bin,
160 /usr/lib/vmware/bin/vmware-vmx
161 vmware_host_pid_t
164 - Set files with the vmware_host_pid_t type, if you want to store the
166 vmware host files under the /run directory.
167 Paths:
170 /var/run/vmnet.*, /var/run/vmnat.*, /var/run/vmware.*
171 vmware_host_tmp_t
174 - Set files with the vmware_host_tmp_t type, if you want to store
176 vmware host temporary files in the /tmp directories.
177 Note: File context can be temporarily modified with the chcon command.
181 If you want to permanently change the file context you need to use the
182 semanage fcontext command. This will modify the SELinux labeling data‐
183 base. You will need to use restorecon to apply the labels.
184
187 semanage fcontext can also be used to manipulate default file context
188 mappings.
189 semanage permissive can also be used to manipulate whether or not a
191 process type is permissive.
192 semanage module can also be used to enable/disable/install/remove pol‐
194 icy modules.
195 semanage boolean can also be used to manipulate the booleans
197 system-config-selinux is a GUI tool available to customize SELinux pol‐
200 icy settings.
